Achieving net zero requires rapid development of technologies such as lowemissions hydrogen, sustainable aviation fuels (SAF), and direct air capture and storage (DACS). The IEA and GenZero report explores how carbon credits can incentivise their deployment. Massive scaling-up is needed: low-emissions hydrogen production needs to jump from almost zero today to 70 million tonnes by 2030; SAF’s share of final energy consumption in aviation needs to rise from close to zero today to around 1
